TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 314,171, dated March 17, 1885.

Applicati n filed January 8, lfilb. (No modehl To all whom it mag poncern:

Be it known that I, VVILLIAM H. ELMER, a citizen of the United States, residing at Berlin, in the county of Green Lake and State of Wisconsin, have invented. certain. new and useful Improvements in Turbine WVater- Wheels, of which the following is a specification, reference being had therein to the accompanying drawings.

7 My invention relates to improvements in turbine wheels, and is designed to produce an easily-operated and efiicient gate for admitting water or preventing the passage thereof to the wheel proper.

The invention is fully set forth in the following description, reference being had to the annexed drawings, in which- Figure 1 represents a plan view of a portion of the wheel; Fig. 2, a horizontal section through the same, and Fig. 3 a detail perspective of the gate-operating mechanism.

The wheel is of any approved construction, and is journaled within a suitable casing, which is provided with tangent openings. The gates are formed of two disks, A, with a side connection, B, and rest in cylindrical hearings in the casing. The connections 13 are of sufficient width to close the opening in the casing when properly placed.

To the exterior surface of the top disk A or disk, I. The

gates having been adjusted to the block 0 by means of the slotted continuation D, through which a portion of the securing devices pass, and the blocks G pivotally set in the disk I, which rests onthem, it is evident that ,turning the said disk I for a distance will cause the gates to turn in their bearings sufficiently to open or close the orifices in the casing.

What I claim is- 1. In a turbine water-wheel, a gate-operating device consisting of a block connected to the gate and having a rod continuation, a partially-rotating disk or plate, and a block pivoted to the same and traveling on the said rod, substantially as and for the purpose specified.

2. In aturbine wheel, a gate operating deon the said rod-extension, substantially as and I for the purpose specified.

In testimony whereof I affix my signaturein presence of two witnesses.
